England international Shaw has not played since November, and was not even included in United's matchday squad for their 4-0 FA Cup win over Reading last weekend — despite being fit.

The 21-year-old has failed to convince new boss Jose Mourinho of his worth and has fallen down the pecking order to the extent he is fourth-choice left-back behind Daley Blind, Marcos Rojo and Matteo Darmian.

Shaw, signed from Southampton for £27million in the summer of 2014, is now fighting to prove he can reclaim his status as United's No1 at the position.

He has made just six Premier League starts this term and has lost his way following his latest injury setback.
